Background. The relevance of the topic is determined by the importance of ensuring the efficiency of verification and certification work and, in this regard, the need to optimize both the structure of verification departments and the planning of verification work. The purpose of the work is to develop a set of models for the construction аnd functioning of a departmental system of verification bodies, which takes into account the main structural and functional parameters of the system of verification bodies. Materials and methods. The article considers a set of models for the construction and operation of a departmental system of verification bodies, which consists of a number of models: the work distribution model allows one to describe the distribution of verification works in the established stationary mode of operation of the serviced objects and verification bodies; the network planning model allows one to describe the distribution of works in time, and the duration of work on servicing applications; the transport model allows one to describe the planning of methods and routes for delivering batches of measuring instruments to verificationdepartments, or the routes of movement of mobile verification laboratories; the system functioning model allows one to describe the processes of performing verification works in a territorially distributed departmental system of verification bodies with various options for constructing the system, distributing and organizing works; the model of expenses and incomes allows one to describe the processes of resource expenditure with various options for constructing verification bodies and organizing works. Results and conclusions. The use of a set of models will allow one to perform a formalized description of the composition and operation of a territorially distributed departmental system of verification bodies, to determine a set of basic system parameters and quality indicators, as well as the relationships between these sets. The considered set of models can be used in the formation and evaluation of options for constructing verification departments and organizing verification works.

Theory of change has become a common tool in project design because it helps teams agree on hypothesized causal pathways to a desired goal and examine their underlying assumptions. Yet, a consensus has not emerged on the specific steps and components of a theory of change. What constitutes a theory of change? Using 22 theory of change publications, we did a structured analysis of the components of a theory of change. Where there was substantial agreement among the publications on a specific component of a theory of change, we included it in the first iteration of our approach. We then ordered the components in a logical sequence, developed guidance for each component, tested them with project teams, and revised them in an iterative process. We tested and refined our guidance over 3 years with 73 teams from 18 countries. Here, we share our learning and recommendations for those interested in developing a robust theory of change for a conservation project. The authors conducted a structured analysis of 22 publications on theory of change, identifying common components to form the basis of their approach. Over 3 years, they tested and refined this approach with 73 project teams from 18 countries, offering guidance and recommendations for creating effective theories of change. [ABSTRACT FROM AUTHOR]

The article discusses a project in Italy that addressed the issue of hexavalent chromium (Cr(VI)) in groundwater in the province of Piacenza. Due to new regulations, an iterative process was developed to assess the problem, identify treatment technologies, define project priorities, and implement solutions within budget and time constraints. The project included site identification, technology choices, intervention planning, and process improvements, resulting in improved water quality and reduced Cr(VI) levels ahead of regulatory deadlines. The project showcased efficient planning and technology selection for successful implementation. [Extracted from the article]

Traditional teaching methods in construction management education often face challenges in providing students with practical, real-world experiences crucial for skill development. To address these limitations, this study explores the potential of integrating building information modeling (BIM) and virtual reality (VR) as educational tools for construction management students. Our aim is to assess the effectiveness of a 4D-BIM-based VR simulation in enhancing student's learning experiences and performance in construction project management. This research employs a mixed-method approach, combining quantitative data and qualitative insights from a comparative experiment involving undergraduate students. Quantitative data were collected through objective error detection measures in construction sequences and processes, while qualitative insights were gathered from participant feedback. The findings highlight that students using VR-based simulations detected more errors in construction sequences and processes than in traditional 2D drawings, showcasing the utility of BIM and VR-enabled approaches in teaching construction management. This study contributes to the ongoing discourse on integrating advanced technologies into educational practices, particularly in construction management, where practical hands-on experiences are crucial for skill development and real-world application.

Artificial intelligence (AI) has helped enhance the management of software development projects through automation, improving efficiency and enabling project professionals to focus on strategic aspects. Despite its advantages, applying AI in software development project management still faces several challenges. Thus, this study investigates key obstacles to applying artificial intelligence in project management, specifically in the project planning phase. This research systematically reviews the existing literature. The review comprises scientific articles published from 2019 to 2024 and, from the inspected records, 17 papers were analyzed in full-text form. In this review, 10 key barriers were reported and categorized based on the Technology–Organization–Environment (TOE) framework. This review showed that eleven articles reported technological challenges, twelve articles identified organizational challenges, and six articles reported environmental challenges. In addition, this review found that there was relatively little interest in the literature on environmental challenges, compared to organizational and technological barriers. [ABSTRACT FROM AUTHOR]

Projects are discussed as social processes that are bounded in both time and space. Elaborating on space is still scarce in studies on project organising. The aim in this paper is to explore space influence on project planning, to extend our understanding of the relationship between space and project organising. Through two illustrative examples, construction project planning practices were followed within and between projects as the actors sought to handle space. Contribution develops current understanding of how projects are embedded in space and its influence on project planning practices, by shedding light on the recursive relationship between space and project organising. Furthermore, to trace planning practice both within a project and between parallel projects visualise how a broader perspective of the embeddedness is necessary. The findings nuance the current understanding of project's embeddedness, by visualising how planning practices can be directed to both changing space or to maintain space by changing practices.

Indonesia is the global coral reef restoration leader by number of projects, yet these remain diverse and disparate. This study reviews the status of Indonesian coral reef restoration within a framework of international common best practice (CBP) that incorporates internationally-recognised Standards for Ecological Restoration (SER). This framework is used to formulate recommendations for a formal network of reef restoration practitioners with the purview to develop and implement a national restoration roadmap. Forty-five projects were surveyed to determine how projects have been planned and implemented. This was compared with recommendations from CBP. There is particular scope to increase quantitative data collection, reinforce community involvement, improve ecological data collection, and standardise monitoring protocols. While 84% of projects reported quantifiable goals, 64% did not quantify goals during planning and 61% did not incorporate climate-smart design features. Quantitative reef monitoring surveys were absent in 22% of projects. The majority of projects did not quantify important ecological metrics like coral community composition/diversity (96%), coral health/bleaching (89%), benthic community (62%), and coral survival (62%). Indonesia has the capacity, regulations, and networks to position itself as a reef restoration driver in the Coral Triangle region; this will require increased coordination, alignment, and quantification of restoration. A structured, collaborative, and iterative national network of various stakeholders would facilitate the development of a national restoration roadmap based on adaptive management strategies. This would aid in standardising project planning, monitoring, and reporting. Efforts should include an increased focus on climate change adaptation goals. [ABSTRACT FROM AUTHOR]

As with many industries, the early life science R&D drug discovery sector is facing growing pressure and higher demands on products in terms of cost, quality, and time‐to‐market. Additionally, the complexity of involved targets and systems, requirements for rapid, safe, and developable candidates are increasing. The drug discovery market, often regarded as rather conservative, relies more and more on advanced technologies. It is therefore a significant task for suppliers to create good solutions that meet customer requirements. The life science industry has a long tradition of using projects as the preferred method to manage these complex systems developments, such as the production of target proteins, screening of compounds, and follow‐up of hit compounds. When applying the project approach, the level of uncertainty is usually high, and the risk of those uncertainties must be managed starting in the early planning phase. Thus, this paper focuses on the issue of how to manage risks in the early project planning phase. We first review state‐of‐the‐art practices in risk management for complex systems project management and identify an important framework, Novelty‐Technology‐Cost‐Pace (NTCP), and apply it to successful risk management for early life science projects. Through an in‐depth case study in the life science industry, we demonstrate a systemic integration of the NTPC framework into project planning. [ABSTRACT FROM AUTHOR]

While the project planning-performance relationship received much attention, the effects of project planning on megaproject performance have not been investigated empirically and little is known about the conditional mediating process between them. This study builds a moderated mediation model to examine the indirect effects of project planning on megaproject performance via process integration and information integration under the contingency of project complexity. 214-megaproject data through a questionnaire survey in China was used to test hypotheses with hierarchical multiple regression and moderated mediation model. Results show that process integration and information integration mediate the positive relationship between project planning and megaproject performance and the mediating effect of process integration is weaker under a higher level of project complexity. This study advances the understanding of project planning-performance relationships considering integration and project complexity. It also offers practical guidance for managers on improving megaproject integration and performance through appropriate planning skills.

The aim of this study was to develop a multi-objective mathematical programming model for the trade-off of time, cost, and quality in the project-scheduling problem (PSP) by taking priorities and resource constraints as well as activity preemption into account. First, a small-sized problem instance that was a sub-project of an oil and gas construction project was used for te validation of the proposed model and algorithm. Subsequently, considering the sensitivity, complexity, and importance of oil and gas projects, the proposed model was implemented in a large-sized oil and gas construction project. Considering the NP-hardness of this problem, the NSGA-II metaheuristic algorithm was used to deal with the time, cost, and quality trade-off problem. Finally, a sensitivity analysis was implemented on the three main parameters of time, cost, and quality to investigate the effects of changes on the results. The findings show that the proposed model is more sensitive to cost changes, so an increase in project costs leads to a drastic change in the values of other objective functions.

This study investigates the impact of change orders on the budgets of 43 public construction projects in the Kingdom of Saudi Arabia (KSA). It addresses the research problem of budget fluctuations in construction projects and aims to understand the causes and consequences of change orders. The research employs a comprehensive methodology involving data analysis from these projects to draw meaningful insights. The major findings of the study indicate that approximately 75 % of the change orders could have been avoided with more effective project planning and management. Owners are found to be responsible for around 40 % of the change orders, emphasizing the need for improved collaboration and communication between project teams and owners during the planning phase. Inexperienced contractors contribute to at least 5 % of the change orders, suggesting the importance of evaluating contractor expertise before project awarding. The study also provides two equations for estimating additional funding or surpluses for public projects, taking into account fluctuations in construction material prices. Moreover, it identifies six critical construction materials and trades, such as thermal and moisture protection, site work, concrete work, conveying systems, electrical work, and mechanical work, which have the most significant impact on project budgets. These insights offer valuable guidance for enhancing project planning, mitigating budget overruns, and optimizing cost efficiency in public construction projects.

There is no significant predictive model that can be used to predict the impact of requirements planning on the success of the residential construction project in literature. The main aim of this research is to find out the impact of requirements planning on the success of the public residential projects in Pakistan. We conducted semi-structured interviews with 29 policy makers in the first part of the study. We also send the questionnaire to 70 construction companies by employing non-probability convenience sampling in the second quantitative part of the study. We received 178 responses. Thematic analysis of the interviews of the policy makers revealed that they define success in terms of project management and product and consider six practices critical for requirements planning. These practices are 1. Advance planning of tracking and reporting of requrements. 2. Configuration Management. 3. Establishment of requirements prioritization process. 4. Use of metrics for performance measurement of requirements. 5. Capturing traceability structure. 6. Clear definition of the roles and responsibilities of the stakeholders who will participate in the requirements management process. We conducted principal component, correlation and regression analyses to analyze the survey responses. The research findings clearly showed that requirements planning positively impacts the success of the project. For the policy makers, requirements planning impacts product success more and for the construction practitioners, it has more impact on the project management success. There is a communication gap between the policy makers and the practitioners. Issues between federal and the provincial governments about land acquisition, political vested interests, project management training issues and the long design phase are the main impediments in the requirements planning. Traditional project management (upfront planning) practices are preferred over agile or lean (incremental planning). [ABSTRACT FROM AUTHOR]

The techniques employed to manage an industrial project are based on tools that aim to achieve the objectives set by an organization. Most of these techniques consider the development of operative and predictive models. The difficulty in developing project planning models relies on estimating large sets of parameters and the need to include model sections of poorly identifiable, that increase costs and time. This work develops a hybrid forecasting model for all the phases that make up die-casting projects through a series of parameters and sub-models that contemplate the particularities of each case, thereby achieving greater precision in the forecast. The model identifies the cost and time factors that affect project planning, specifically in the die-casting industry, and intends to predict their future behaviour when certain initially given conditions are modified. To estimate the parameters of the hybrid model, several factors in the processes were considered that interact in this industry, such as primary matter costs and activities associated to the process. The considered processes that have a substantial economic impact on the implementation of the project were selected. The criteria for this selection considered identifying the relevant parts of the design and manufacturing in the diecasting industry. Process factors such as the Cost of aluminium and its related activities, whose processes will be grouped into cost and time entities to build a set of metrics that allow better control over them. Finally, the proposed model is based on analytical, parametric, and analog methods that achieve accuracy greater than 85 % in predicting the time and Cost of the process. [ABSTRACT FROM AUTHOR]

Planners face many obstacles during the planning phase of any new project, especially project scheduling due to the numerous details and complexity of each uniquely designed project; previous experience in similar projects and traditional scheduling methods are not sufficient. The 4D-BIM schedule is the best solution, as it can be integrated with other modern technologies such as UAS, which improves project scheduling by allowing the project team to access project plans, details, and time-related information to simulate construction sequences. Despite the benefits of using 4D-BIM, planners prefer traditional planning and scheduling methods because of the barriers to using modern technologies. This research proposes a structural equation model focusing on estimating the weights of BIM barriers in offshore construction projects, including: the investigation of barriers keeping the construction industry standing at 3D-BIM; the relationships between them; and the evaluation of the probability and impact of each, using fuzzy theory. To validate the proposed model, a case study of an offshore project was conducted. The most important latent variables were awareness, risk, demand, and management, while the most prominent observed variables were the uncertainty of the return on investment and the lack of experienced users. This research guides project managers on actions that can be taken for each key variable to enhance and develop the use of 4D-BIM in project scheduling. [ABSTRACT FROM AUTHOR]

The Chinese government is actively pursuing a low-carbon development model with a clear target of reducing carbon dioxide (CO2) emissions by 2030. This study presents a project-based perspective on CO2 emissions from the industrial sector in the city. The article quantifies and analyzes the project planning by including the entire gross industrial production value, industrial structure, energy intensity, energy structure, and CO2 emission coefficient of the industrial sector's CO2 emissions decomposition model. Monte Carlo simulation and scenario analysis were coupled to evaluate how the city's industrial sector could achieve its peak carbon targets by industry. The expected range of CO2 emissions from the city's industrial sector in 2025, 2030, and 2035, based on the project plan and policies in place, is projected to be between 65.64 and 69.26 Mt, 72.13–78.48 Mt, and 69.32–76.62 Mt. However, the simulations show that there are still considerable uncertainties in reaching the peak carbon target in 2030, necessitating greater government efforts. To achieve the 2030 goal for the city's industrial sector, the paper recommends that the government increase the baseline criteria for industrial structure, energy intensity, and energy structure. This study provides scientific project planning guidance for Chinese cities to successfully achieve the 2030 goal.

Although information systems development (ISD) projects are critical to organizations and improving them has been the focus of considerable research, successful projects remain elusive. Focusing on the cognitive aspects of ISD projects, we investigate how and why mutual understanding (MU) among key stakeholder groups (business and information technology managers, users, and developers) changes within and across projects, and how it affects project success. We examine relationships among project planning and control mechanisms; sensegiving and sensemaking activities by, and MU among, these stakeholder groups; and project success. Combining deductive and inductive approaches for theory building, we develop an initial model based on the literature and then modify it based on the results of a longitudinal embedded mixed-methods study of 13 projects at 2 organizations over a 10-year period. The results provide insights into the development of MU within projects, including (1) how MU changes during projects as a result of cognitive activities (sensegiving and sensemaking); (2) how planning and control mechanisms (and the associated artifacts) affect these cognitive activities; (3) how MU, and achieving it early in the project, affects success; and (4) how stakeholder engagement (in terms of depth, scope, and timing) affects the relationships in (1) and (2). The results also indicate that project management mechanisms, stakeholder engagement, and MU may change (either improve or deteriorate) across projects, depending on the disagreements among stakeholders in previous projects, the introduction of new project elements in subsequent projects, and the reflection on previous projects.

The purpose of this article is to provide a brief review of methods and techniques developed for the most commonly studied decision-making problems in project planning and control over the last decade. These problems involve project representation, project scheduling, resource allocation, risk analysis, time and cost performance evaluation, time, cost, and cash flow forecasting, optimal timing of control points, and corrective action decision-making. We also review recent tools developed for project planning and control. The emphasis is on recent contributions, but several older yet important works are also cited. Our analysis shows an increasing attention to the stochastic nature of projects in planning and control decision and processes. Recent attention has also been put at improvements in existing project control techniques as well as developing new methods to automate data collection, process, and generate more integrated project plan. More importantly, our review highlights an important shift in the project planning and control research field, which has been largely dominated by the project scheduling literature in the past, as short term and reactive decision-making bring new challenges and opportunities to project organisations and researchers.

The Success in the use of the Primavera P6 Software to schedule the project depends on the size of the project, the level of its complexity the time allocated for its execution and the requirements dictated by owner of the project……etc. The basic idea behind the proposed system is the use of software set up for this purpose in order to delineate start- finish time by applying Critical Path Method, the Primavera P6 Software for scheduling single constrained resource in projects. They may only of solutions start by scheduling and analyzing the resource time period by time period, and resource by resource when the amount of the resources available is exceeded the method of tasks is examined and rare resources are then allocated according is the levels of priority. A major position arises then: how to increase the time necessary for the completion of the project with the remaining minimum with due respect to the labor limitations. The answer lies in the application of the Primavera P6 Software which is used in practical situations, so as to avoid mathematical complications which are characteristics of perfect model methods. In order to achieve the best solution, activities are re- scheduled based on labor constraints according to various numerous bases. These were applied on a project for the construction of a small size Gas Station, classified under small construction projects which include 29 activities. The 3 stages of implementation were applied tested to the project mainly planning, scheduling and control. We obtained the desired results with an increase in the time allocated for the completion of the project with strictest minimum possible while respecting labor constraints.

The article is a continuation of regular research on project management based on efficient transportation. The purpose of the work is to improve the efficiency of management decision-making in the implementation of projects in transport logistics through the use of automated planning and analysis systems. The object of study is the process of forming organizational support for project management in transport logistics using automated planning and analysis systems for project efficiency. The subject of the study is the practical tools for organizational support of project management in transport logistics using automated systems for planning and analyzing project performance. Methods. In the course of the study, a systematic approach was implemented, general scientific methods were used, including logical analysis, synthesis, induction, deduction, analogy, and modeling. The theoretical and methodological basis of the study is the fundamental provisions of project management, management efficiency theory, scientific works of domestic and foreign scientists on project management at the micro, meso, and macro levels. Given the purpose of the work, several tasks were set and solved, in particular, the applied imperatives of resource and budget planning were outlined on the example of a logistics center based on the Odesa seaport and the project implementation was monitored in Microsoft Project. In terms of resource and budget planning, the expediency of using the method and indicators of the volume utilized is proved. The actual progress of the project against the planned indicators is analyzed. A new project was created using the Microsoft Project software and data entry method. In terms of monitoring, conclusions were drawn on the course of events in the project implementation and the status of implementation by individual types of work was clearly shown. All this made it possible to achieve concrete results. In terms of resource and budget planning, it was determined to what extent there is a deviation from the planned project implementation timeframe. In terms of monitoring, the need to optimize staffing, budget, and time parameters was identified. The essence of this optimization boils down to the decision to attract additional labor resources with the corresponding cost of work per hour. This made it possible to get rid of the conflict and obtain positive dynamics in the project implementation, as evidenced by the date of its completion, which remained unchanged after the resources were equalized. The need to continue the study and focus on project risk management is outlined.

The object of research of this work is the processes of project planning and monitoring. The solved problem is the development of a model, method and structures of a multilingual intelligent project planning and monitoring system and its experimental verification of the ability to understand the statements of managers in different languages. The requirements for such a system are formulated. An analysis of the existing theoretical and practical developments in this area was carried out. It was established that there are no developments in the field of project management that can adapt to new natural languages. It was found that the formulated requirements can be satisfied within the framework of the reflexive approach. It is characterized by simplicity, continuity, and insensitivity to errors in natural language statements. To confirm these assumptions, an experimental multilingual project planning and monitoring system and experimental research methodology were developed. The results of the experiments obtained during the use of the created experimental system testify to the correct identification of the content of appeals to the intellectual system in 6 languages with a probability higher than 0.99, and to recognize the structure of statements with a probability higher than 0.98. And the time for configuring the system to work with a new language did not exceed 1 hour. This allows to use it for practical work in distributed management systems for remote interaction of managers and specialists with the system in different languages. The conducted experiments confirmed the assumption about the effectiveness of the reflexive approach for creating project management systems. The developed model, method, structures, and system can be used for different types of projects, such as regional development projects, IT, etc. [ABSTRACT FROM AUTHOR]

The construction industry has been suffering from delays and cost overruns for decades. Experienced schedulers programs and allocate contingencies (both cost and time) based on professional experiences and gained knowledge. Such tacit knowledge has not been captured, stored, and shared with inexperienced schedulers. This paper proposes a graph-based automated scheduling (GAS) method to capture, store, and reuse the tacit knowledge in the construction schedules. The proposed GAS method takes construction schedules as input, extracts schedule features, classifies schedules into different types of sequences, selects and assembles sequences into schedules, and eventually optimizes time- and cost-efficiency of assembled schedules. The GAS method was validated on two case studies. The results indicated that the automatically generated construction schedule is, on average, 6.70% closer to the actual schedule than the planned schedule. Different from existing automatic scheduling methods, GAS relies little on the availability and data richness of building information modeling (BIM) models. Hence, GAS helps schedulers initiate new schedules more efficiently at the early construction stages. [ABSTRACT FROM AUTHOR]

Establishing realistic project plans and completing the resulting business projects on schedule is crucial for organizations striving to effectively utilize their resources. However, incentivizing on-time project delivery may result in moral hazard, as people could respond to estimation accuracy incentives by strategically inflating duration estimates and subsequently prolonging project execution. While the project is delivered on time, the resources are underutilized. We conjecture that the possibility of moral hazard can be mitigated by introducing speed incentives in addition to the schedule accuracy incentives. We conduct a diagnostic test of the effect of accuracy and speed incentives on the process of project estimation and delivery. Our study presents direct empirical evidence that the incentive structure rewarding solely the estimation accuracy can result in hidden inefficiency due to inflated estimates and deliberately slower project execution. When speed incentives are implemented alongside estimation accuracy incentives, the estimates are significantly lower and the project is completed more quickly, without compromising the schedule accuracy or output quality. Aligning the objectives of a project owner with those of planners, by incentivizing the planners for both estimation accuracy and quick project completion, fosters more compressed but still accurate and reliable project schedules, and accelerated project delivery.

Planning-performance theory suggests that formal planning has a positive impact on performance. Accordingly, traditional project management methodologies advocate formal planning as an essential process in any project. However, alternative recent project management methodologies (e.g., Agile) promote less focus on a formal planning process at the start of a project. In this article, we question when formal planning is effective, when it is counterproductive, and which planning approach (strategic or tactical) is more effective for various project risk levels and performance dimensions (efficiency and effectiveness). Results from analyzing 2002 projects suggest that strategic planning has a higher value than tactical planning. Furthermore, tactical planning has a negative impact on project efficiency in low-risk projects as it increases project duration and cost but adds little value. In practice, in low-risk projects, managers may limit their focus on counterproductive tactical practices, such as risk, and procurement planning, and focus instead on long-term strategic planning, such as human resources planning. Theoretically, this article sets boundaries of effectiveness for planning-performance theory and advances the literature on the planning fallacy. [ABSTRACT FROM AUTHOR]

Carefully considering the Capability Maturity Model Integration (CMMI) Level 2 specific practice to “define project life cycle phases” (SP 1.3) is a key requirement, particularly when it comes to small and medium-sized software development organizations. This is a necessary step to help these organizations get nearer to achieving CMMI Level 2 certification. In this paper, we, therefore, report on our latest empirical study that recently explored both the perceptions and experiences of practitioners about SP 1.3 implementation. During our research, we visited three firms and carried out three in-depth interviews. We developed a SP 1.3 model using the different experiences and opinions of practitioners regarding SP 1.3 implementation. The four essential stages of this model are plan, design, review, and update/rework. Practitioners will receive advice in this model about implementing SP 1.3 effectively.

The article deals with the problems of climate change and global warming, extreme climate phenomena, which present risk factors for the national economy, including construction. The causes that lead to the occurrence of the construction degradation phenomena are diverse and may be specific to improper exploitation, but also as a consequence of extraordinary natural phenomena or results from the humanity’s interrelationship with the environment. The degradation of the constructions is manifested by the gradual loss of the physical and functional qualities that characterize the aptitude for their exploitation, the degradation process manifesting itself starting from the contact surfaces of the constructions with the environment. Urban planning and the design of adequate infrastructure play an important role in minimizing the impact of climate change and reducing the risk to the human environment. The undertaking's measures, which will consider the potential impact of climate change on buildings, will provide opportunities for new markets for climate change-resistant technologies, machinery, materials, and products.

Background. The article discusses the features of the functioning of projectoriented organizations in a competitive environment. The specifics of projects is described in which the main category of resources is specialists, and not material and technical means. At the same time, quite often the determining criterion for the feasibility of a project is the availability of a sufficient number of specialists with the necessary skills and knowledge to perform the tasks of the planned project. In turn, the ability to carry out projects with sufficient or higher value significally affects the effectiveness of the functioning of a project-oriented organization and its competitiveness. Materials and methods. Genetic algorithms, computational experiment. The article introduces the concept of competence potential and its role in the functioning of a project-oriented organization. A general method for managing the competence potential of a project-oriented organization is described, which makes it possible to determine the feasibility of developing specific competencies of employees, taking into account the portfolio of projects, individual preferences of employees and the strategic goals of the organization. The method for determining the target state of the competence potential in the analysis of the project for a particular case is described. Results. The application of the proposed method for determining the target state of the competence potential in the analysis of an IT project is demonstrated. Conclusions are drawn about the applicability of the proposed method of managing the CP in the context of managing a portfolio of IT projects. Conclusions. Further plans and directions for the development of the proposed competence management general method are presented.

As project teams become more global and culturally diverse, it is important for project managers to understand how various project management practices are implemented in different countries. We use hierarchical linear modelling to explore variation in project management practices among seven countries using GLOBE dimensions of these countries to understand patterns. Of the nine GLOBE dimensions, two particular elements had an impact on project management practices. Performance orientation has a significant positive influence and gender egalitarianism had a significant negative impact on the adoption of project management practices. Practical implications include that for those two specific GLOBE factors, executives and project team leaders should use such knowledge to anticipate how they will impact on the natural tendencies of project team members in various countries, Further, when operating projects with international team membership, such as global virtual teams, this study illuminates that some cultural differences might lead to differences in style and practice of project team members, requiring cognizant and careful team leadership. The article contributes to theory by showing that only some and not all aspects of national culture impact on project management practices that are theoretically deemed attractive as part of project management's body of knowledge.

The developers of the construction project assess the economic feasibility of the project at the early stages of project development and analyse possible alternative solutions. This research focuses on the assessment of property attractiveness and building location problems at an early stage of project development and proposes the original method for visibility analysis based on the utilization of Building Information Modelling (BIM), Geographic Information System (GIS) and Web environments. The proposed Quantitative View Assessment (QUVIAS) method allows to assess the view mathematically and presents it as a quantitative parameter. The proposed method considers the mathematical shape of the view as a sphere and utilizes spherical coordinates that remove distortions and increase the accuracy of the analysis. The presented approach determines quantitative view coefficients for alternatives of windows, premises and buildings, including their comparison. The way of determining the view proposed in the QUVIAS method can help decision-makers to make more accurate decisions during the selection of a project development strategy. The experimental analysis proved the usefulness of the proposed QUVIAS method in the assessment of the rational building location and prediction of project revenues as well as potential usefulness in the estimation of property attractiveness.

Building Information Modelling (BIM) can be defined as a set of tools, processes and technologies that are enabled by a digital multi-dimensional representation of the physical and functional characteristics of a built asset. The ‘fourth’ dimension (4D BIM) incorporates time-related project information in the 3D model to simulate and optimise the project construction process. To achieve this, the 3D objects within the aggregated design model must be linked with each activity in the construction schedule. However, the levels of maturity and expertise in using BIM amongst the project participants still varies considerably. This generates collaboration problems within the project and adds further obstacles to the ability to derive full benefits from BIM. Ideally, 4D BIM can be automatically generated, but in reality, because the 3D and 4D models are created separately and at different stages of the project, this is not currently possible, and the process requires considerable manual effort. The research reported in this paper was prompted by the construction of a new training and research building: the Nanterre 2 CESI building in France. It proposes an efficient approach that minimises the effort of creating 4D BIM construction schedules. The CESI four-phase process aims to help project participants to fully exploit the potential of 4D BIM and enables: 1) a clear expression of the 4D BIM objectives; 2) the identification of information requirements and relevant workflows to achieve these objectives; 3) the implementation of a project schedule; and 4) BIM model production to suit the 4D BIM use case. Although the CESI approach was developed in the context of the French contracting system, the observations and conclusions of this study are intended to be generally applicable.

Planners face many obstacles during the planning phase of any new project, especially project scheduling due to the numerous details and complexity of each uniquely designed project; previous experience in similar projects and traditional scheduling methods are not sufficient. The 4D-BIM schedule is the best solution, as it can be integrated with other modern technologies such as UAS, which improves project scheduling by allowing the project team to access project plans, details, and time-related information to simulate construction sequences. Despite the benefits of using 4D-BIM, planners prefer traditional planning and scheduling methods because of the barriers to using modern technologies. This research proposes a structural equation model focusing on estimating the weights of BIM barriers in offshore construction projects, including: the investigation of barriers keeping the construction industry standing at 3D-BIM; the relationships between them; and the evaluation of the probability and impact of each, using fuzzy theory. To validate the proposed model, a case study of an offshore project was conducted. The most important latent variables were awareness, risk, demand, and management, while the most prominent observed variables were the uncertainty of the return on investment and the lack of experienced users. This research guides project managers on actions that can be taken for each key variable to enhance and develop the use of 4D-BIM in project scheduling.

• Introduced a graph-based recommendation system using node2vec for optimized construction management. • Model trained on activity-resource networks for ranking resources of an activity. • Facilitates informed decision-making by offering data-driven insights tailored to diverse construction scenarios. • The proposed approach minimizes guesswork, streamlining project planning and productivity management. The escalating volume of data in engineering practice necessitates innovative computational approaches for data-driven insights. Existing literature relies on isolated data points, unable to exploit the inherent connectivity in engineering datasets, resulting in suboptimal utilization of data context. This research employs node2vec, a graph-based recommendation system that surpasses existing models by incorporating an efficient walking mechanism to learn from past behaviors and a predictive component that enhances its adaptability. By structuring these activities into a network of budgeted units, person-hours, and earned values, the effectiveness of the node2vec model as a resource recommendation tool was demonstrated across three diverse datasets. Firstly, node2vec efficiently explores diverse neighborhoods within the input network through a flexible biased random walk, enhancing the system's ability to adaptively model complex relationships among various project elements. Secondly, this graph-based approach allows the recommendation models to fully harness relational data. These mechanisms coupled with a predictive neural network component enabled node2vec to learn from and utilize data connectivity, achieving an accuracy rate of 94% across the datasets. Ultimately, by leveraging collected engineering data and recognizing dependencies among records, the system can offer more detailed insights and empower engineering managers to make better-informed decisions.

Optimizing work package schemes is challenging under uncertain task duration. This paper develops a two-list genetic algorithm (TLGA) to optimize work package schemes with minimal project costs under deterministic and stochastic task durations. First, this paper defines the deterministic and stochastic work package scheme problem. Second, the TLGA, comprising a task and a work packaging list, is developed to generate the deterministic work package scheme and issue work package policies through stochastic distribution simulations. Moreover, a graphical user interface with TLGA is developed to enhance its practical application. Finally, experiments show that the TLGA can reduce the total cost by up to 19.57% in the deterministic problem, and the minimum gap between the TLGA and the state-of-the-art heuristics is only 3.91%. However, the TLGA can reduce the running time by about 66%. In the stochastic problem, this paper analyzes the impact of stochastic distributions on work package policies. • The TLGA is proposed for generating work package schemes or policies. • TLGA can process uncertain task durations with stochastic distribution simulations. • The minimum gap between TLGA and state-of-the-art heuristics is only 3.91%. • The running time of TLGA can be reduced by about 66% through parallel computing. • The impact of stochastic task durations on work package policies is analysed.

Project performance of the construction sector can be significantly improved by proper project planning and scheduling. A divergence opinion is included in this area which implies the amount of effort that is required or should be invested in construction planning and scheduling activity to make the project management effective. A lot of work has been already reported in the literature which clearly shows that the project performance can be enhanced by raising the efforts invested in project planning, scheduling, and controlling activities. The organizational characteristics of the construction firms and the project environment have a great influence on planning and scheduling efforts. The firm should be organized appropriately to maintain a relevant environmental context in the project planning. In India, after agriculture, it has been notified that the construction sector is the second largest employment sector. Also, it has been considered as one of the largest sectors which support the economic growth of the country. The magnification of the construction sector is based on the growth of the corporate sector and infrastructure development either directly or indirectly. The construction sector generates employment and provides job opportunities to millions of unskilled, semi-skilled, and skilled workforce. When it comes to the economic development of the country and a large labour force are engaged in this sector, definitely a high work effort we can consider from appropriate project planning activity. To keep in mind the importance of project management in the construction sector, our study is focusing on the relationship between construction planning efforts and their effectiveness in the field of project performance. Software used for Construction Project Management (CPM) is also discussed. [ABSTRACT FROM AUTHOR]
